I think the campag system of the lockring coming with the hub is should be better (bit cheaper) than every Shimano cassette having a new lockring (except for this 11-12 Campagnolo diameter discrepancy)
Agreed 'latman' - it's a vastly more sensible system [as usual], but you could see my dilemma......enthusiastically purchase thinking nothing of missing lockring, then, on arrival there's the 'oh shit' moment when you realise there may
be a difference and you now have to find one.
Don't even know if a steel one would have got me out of jail - the Ti cassette uses a Ti lockring, obviously. And loose, they cannot be easy to find!
I'm relieved to say the least. Thanks for your input.
